APPARATUS FOR THE MANUFACTURE OF CARBON BlSULPHiDE.

SPECIFICATION forming part of Letters Patent No. 321,662, dated July7,1885.

(No in: do!) To (ZZZ whom it may concern:

Be it known that I, EDWARD R. TAYLOR, of Cleveland, in the county ofCuyahoga and State of Ohio, have invented certain new and usefulImprovements in Apparatus for the Manuthcture of Bisulphideot' Carbon;and I do hereby declare the following to be a full, clear, and exactdescription of theinvention, such as will enable others skilled in theart to which it pertains to make and use the same.

My invention relates to improvements in apparatus for the manufacture ofbisulphide of carbon; and it consists in certain features ofconstruction and in combination of parts hereinafter described, andpointed out in the claims.

In the accompanying drawings, Figure 1 is avertical section of myimproved apparatus through the center of the retorts and longitudinalwith the furnace. Fig. 2 is a front elevation of the same, with theattached pipes and condensing apparatus shown in section. Fig. 3 is avertical section of condensing-tubes that are a continuation of thoseshown in Fig. 2. Fig. 4. is a View in perspective of the lower retort.Fig. 5 is a longitudinal vertical section of the same. Fig. 6 is anenlarged vertical section of a portion of the said lower retort. Fig. 7is an enlarged vertical section of the man-hole plate.

A represents the main retort, and consists of a hollow castiron cylinderprovided with an upper head and man-hole plate, A, that has an opening,a, of considerable size, that is closed by the stopper a". This stopperis preferably in the form of two cones united at their base and providedwith a long handle. By means of this peculiar shape the stopper iseasily drawn up through the charcoal and as easily returned to its seat.The part A is also provided with the flanged nozzle A, for theattachment of pipes, as hereinafter shown. The part A is open at thelower end and rests upon a sub-retort that is also of cast-iron, and hasa hollow rectangular part, B, and an upright hollow cylindrical part, B,that are integral and their respective inclosed chainbers in openrelation with each other. The

part B is closed at the bottom and open at the top, as shown in Figs. 1,4, and 5, and has an offset upwardly-projecting flange, b, leaving ashoulder, I), on which the part A rests, and a tightjoint is made bypacking clay or other refractory material between the flange Z) and thepart A. The front end of the part 13 extends through the furnace-front,and is provided with hook lugs b", that hold the cross-bar If. This barhas a set-screw, b, in the central part that holds the head or cover B"against the end of the part B, as shown in Fig. 2, thejoint between theparts B and B being also packed with clay or other suitable material.The sub-retort rests upon the arch D,that spans the firebox laterally,but is less in length than the firebox, leaving a space at either end ofthe arch for the upward passage of the products of combustion, as shownin Fig. 1. On top of the retort A is secured the cylindricalchareoalcontainer 0, provided with a removable cover, O, and is inclosedby the jacket I, that is provided with the smoke pipes c, and extends tonear the bottom of the part- 0, where it'joins the brickwork, as shownin Fig. 1.

E is the tire-box, E, the grates, and E a plate covered onv top withbrickwork, over which the fuel is passed to the grates. The grates, asshown, are located some distance from the furnace-front, so that moreheat will pass up the rear passage-way and around the retort A, wherethe greatest heat is required. The furnace is provided in the usualmanner with the furnace-door c and the ash-pit door 0.

F is a pot for melting sulphur, and has a removable cover, F, and has ahole atthe bottom closed by the stopper f. A flaring tube, j, conductsthe melting sulphur to the subretort. This tube is liable to becomeclogged with the sediment from the sulphur, to pre vent which the tubeis considerably larger than the hole leading to it from the sulphurpot,and increases in size toward the sub-retort, as shown. This tube isusually located near one side of the pot, so that the handle of thestopperf is more out of the way. The brick setting G inclosing theretort is, above the furnace, preferably pyramidal, so that the hot-airchamber E around the retort A is contracted about the upper end of theretort, and the heat thereby more or less confined in the chamber. Thewalls extend above the retort A, as shown, so that the chamber His inopen relation with the chamber it that surrounds the container 0. Thefront wall is breasted out at G and made to inclose the chamber H aroundthe sulphur-pot. A flue, I,connects the chambers H and II, and may beprovided with a damper, 77, to control the amount of heat admitted tothe chamber H. The tubes that conduct the vaporized products from theretort Ato the condenser have usually been the source of much annoyance.The expansion and contraction of the parts rendered it extremelydifficult to keep tight joints at the ends of these tubes; also, thesetubes are liable to become clogged with free sulphur that is carriedover with the volatilized products. To remedy these difficulties, I havedevised the following-described mechanism: To the flanged nozzle A Ibolt the flanged end of the angular pipe J, one leg of which isvertical, as shown in Fig. 2, and has near the bottom attached thevertical cup J, the depending rim of which extends into the annularrecess or cup is of the sulphur-box K. The cup in is filled withglycerine or other liquid that will retain the vapor in the box andexclude the air. The tube J may, therefore, be raised or lowered atrifle by the expansion or contraction of the retort without injury. Theupper ends of the part J are provided, respectively, with the removablestoppers j. These stoppers may at any time be removed, and the freesulphur that is lodged in either leg of the pipe may be removed by ascraper, the straight legs in line with the respective stoppersrendering all parts of the tube accessible. The volatilized productsthat pass through the pipe are heavier than air and will not pass out atthe upper end of the pipe when the plugs are removed. A pipe, L,provided with the stoppers Z, arranged similar to those just described,and for the same purpose, leads from the box .K to the condensing-tubesM. The latter is a long tube of considerable size, provided at eitherend with a stopper, N, and is submerged in a tank of water.

In operating the device the pot F is charged with sulphur and the retortA with charcoal, and a quantity of the latter is had in reserve in thecontainer 0. After the charcoal has become sufficiently heated in theretort and the sulphur is melted in the pot F, the stopper f is raised,and a quantity of the sulphur is discharged through the tube f into thesubretort and at the part that is directly over the front passage-Wayfrom the furnace. The

heat at this part of the subretort is sufficient to volatilize thesulphur, which, passing through and combining with the heated charcoalin the retort A, forms the bisulphide of carbon, that passes off throughthe tube J to the box K, and from thence through the tube L to thecondensing-tube M. Any excess of volatilized sulphur that does not thuscombine with the charcoahand that is carried off with the other vapor,will be condensed and collected as free sulphur in the box K,from which,from time to time, it may be removed. As the charcoal in the retortAbecomes exhausted of carbon,by raising the stopper a a fresh supply maybe introducedfrom the charger O, f

and the charger may in turn be replenished by raising the cover 0. Thecharcoal in the charger becomes heated by what would otherwise be wastedheat, that passes from the chamber H through the chamber h, and'whenintrcduced into the retort does not retard the chemical union theretaking place. Sulphur may from time to time be added to the contents ofthe pot F, so that there will always be a supply of melted sulphur, andthe process of manufacturing the bisulphide of carbon is thus madecontinuous.

\Vhat I claim is 1. In an apparatus for the manufacture of bisulphide ofcarbon, the combination,with a furnace, a vertical retort locatedtherein, and a container located above the retort, of a sul phur-box,pipes connecting the retz rt and sulphur-box, and condensing-tubesconnect(d with the sulphur-box.

2. In an apparatus for the manufacture of bisulphide of carbon, thecombination, with a furnace, a vertical retort located therein, and acharcoal-container located above the retort, of the sulphur-box having aflanged opening, a cup surrounding said flanged opening, pipesconnecting the retort and sulphurbox, and provided with an inverted cupthe lower edge of which rests between the flange and the cup of thesulphur-box, and a pipe leading from said sulphur-box, substantially asset forth.

In testimony whereof I sign this specification,in the presence of twowitnesses,this 19th day of June, 1884.
